COPYING-ne ulae.

To alA whom it may concern.-

Be it known that I, RAPHAEL Seuw ERs, a

- subiect of the German Emperor, residingat ceiving the cut copies from the web.

Four forms of construction are illustrated in the annexed drawings.

Figure 1 illustrates in vertical section a machine having a horizontal feed-table, an automatic feed-roller, and an adjusting and stop plate, and a receiver for the cut copies at the end of the machine opposite to the feed-table. Fig; 2 illustrates in a similar manner a machinehavin v an inclined feedtable and an adjusting-p ate. Fig; 3 illustrates in a similar manner a machine having the same parts as described with regard to Fig. 1, but differently arranged. Fig. 4 illustrates also in vertical section a machine in which the feed-table is at the same end of the machine as the receiver for out copies.

The machinefiaine, cutting device, cop'ying-cylinders, water-receptacle, and various other parts are similar to the corresponding arts described in the specification of my Former United States patent, No. 770,321, dated Se )tember 20, 1904. v

The advantage secured by the automatic adjustment and feed of the letters between the copying-cylinders arises from the fact that it renders it unnecessary for the operator to pay special attention to inserting the letters into the-machine in such a manner ing the subsequent letter after that each letter to be copied reaches the copylng-c linders at the moment at which the last etter copied leaves the said cylinders. The automatic adjustment allows of inserta much briefer interval, and sullicient time ,is thus made available to insert the lette s without stoping the machine. This is more particulhrly of importance in the case of copyingmachines in which the copies are automatically cut from the web.

In all the construct-ions illustrated 8 Visa roll of copying-pa ml, the web 9 of which passes under the roller 53 in the water-receptacle 54 and travels to the squeezing-rollers Specification of Letters Patent. Application filed August 12.1905. Serial1o.278,97.

tothe eopyingv is the oscillatory feed device vice at the desired moment, the roller ..2 is preferably s o calculated that it Patented Nov. 1a, 1900.

is rotatable about the axle 14. Shortly before the Cuttin operation begins the bow 13- is moved into the position shown in full lines in Fig. 1 and presses the cup;' 10 to be cut off against the xed bar-17. he up r part of the copy cut off falls back overthe ow 13, over which the copy remains suspended whereupon the bow tween it and the bar 17, whereupon the operationis repeated.

20 is the table on which the letter to be co ied is placed.

n each form of construction illustrated 6 which aiitomatically inserts the letter rollers. The oscillatory movement ofthls l3'returns' to its original position and allows the next copy to pass. be-

between the copyihgdevice is produced periodically. When the feed device 6 has been raised, the letter next to be copied can immediate]; be placed thereunder and adjusted with its forward edge against the guide and stop-plate 18 Figs. 1, 3,'or 4, or against the copying-rel er itself, Fig. 2. The'automatic. insertion of the letter into the machine begins from this predetermined position. Y 1

The diameter of the copying-roller 2 is so proportioned to the length of the letter-paper that at the same moment at which the pre-- vious letter 22 passes ers the roller 6 descends and moves the next letter 21 between the diately behind the letter 22.

To secure the action of the inserting dethe diameter of" makes one revolution duringthe copying of a letter. If a cam, such as 41*, is properly adjusted on the axle of the roller 2, with a ridge with a. projecof the proper lengthin. contact vice, the latter is'opened at the proper mo-. ment during the copying of a'letter for the insertion of the following letter and closes at 1 IO the-proper movementby' gravity for the punpose of inserting the latter. Y

copying-rollers immefrom between the rollloo -'tion 42'on the frame 19 of the insert ng de- Y ers. in Fi 1, .3 id 4 th:: pl H hinged to tr; '1 i ll), n r es the d d ire c rests loosely in l n roller 2, in Fig. 3 on table 20, and in l 1,; 4 on roller 25. As the frame l9 moves up and down the plottl8 hollows thecontou'r of the roller or table on which its lower and outer end rests. in Fig. .2 the plate 18 is lixed to the ironic l9 but it also in following the movement of the frame 'l moves sthwert the plane of the table 20, and so deflects the letter when it is to be fed between the rollers 2 and 'lhe vi-u'ious parts of the machine are driven by it hand-crank 43 on shaft 44. This drives the roller 2 by pulley-strep 45. liollcrs 1 .ltllilf ii are driven hyhiction from roller 2. 'ltoller 6 revolves by friction when it 'ltllS into contact with roller 2, Fig. 1, or with roller 3, Figs, 2 and 4, or with a special roller 40, Fig. 3.

iulley-strzip 46'. Roller l is driven by pullcy-stm )s 47. Roller revolves by friction with roller 4. y- The knife is moved by henddcver 33 and link 32. ee Fig. 3.) The how 13 is rocked in'one direction by cord B l, attached at one end to lever and ut the other to the how 13 and passing round ii pulley 35, zmdin the other direction'hy a spring 3% What l cleiin ttS' my invention, and desire to secure by Letters Patent of the United States, isf i. In a copying-n1achine the combination with. it plurality of copyingd ollcrs, a 'lisplttceuhle iced device comprising u. roller and :1 plate, and meens connected with the copyiug rollers for l ringingscid feed device into mtlffll and moving said plate at an interval equivalent t e pre lcterniincd distance of revolution of the copying-rollers and for moving said iced device ont'ol action and restoring said plate to itsprevious position after at.

shorter inter vol.

2. in :1, copying-machine the combination with 5L plurality of copying-rollers, of e dis pluccnhle fved dcvicc comprising a roller and EL greyity-opemted stop-plate, and means connected with the copying-rollers for bringing: said iced device into action and moving;

between the con ing-roll- Roller 40 is driven by said stop-plate so as to form. a, guide at an intervsl, equivalent to a predetermined distence of revolution of the copying-rollers and for moving said feed device out of action and restoring said stop-plate to its stopping position after a shorter interval.

3. In a cop nngnneclnne the combination with a plurality of copying-q llers all a disphiceeble feed device comprising it movable feed-roller end copying-rollcr and adopted to i opercte as c letter stopwhen the feed-roller is out of operation and as a letter gnide when th 5 cd-roller is in operation. i

5. In a copying-machine the combination With a plurality of copying-rollers, 9, Webroller, c waiter-trough, a pair of cutters, an

oscillatory receiving-bow for the cut copies,

and means connected with the cutters for op erating said how.

6. In a copying-machine the combination with a. plurality of copyingqollers, a. webroller, a ater-trough, a pair of cutters, an oscillatory receiving-bow for the cut copies, moons connected with the cutters for operating-seid how, a displacccble feed device comprising. a roller and a gravity-operated stopplate and means connected with the copying rollers for bringing said feed device into action and moving said stop-plate at an interval equivalent to a predetermined distance of revolution of the copying-rollers and for moving said feed device out of action and restoring said stop-plete after a shorter interval.

.7. In a copyin machine, the combination, with o plurality of copying-rollers, of a guideplate positioned with regard to said rollers so that a letter to be copied resting on said plate abuts on one of the copying-rollers, and means for displacing said guide-plate to deflect the letter between the copying-rollers.

In witness whereof I have signed this speciiicetion in the presence of two Witnesses.
